Bottom Line: The article presents the measurement results of the volumetric activity (VA) of artificial radionuclides (90)Sr and (137)Cs in the coastal waters of the Baltic Sea near the Curonian Peninsula in 2005-2009.Considerable variations in the VA of the radionuclide in individual measurements compared to the average results were observed.Besides, a possibility of penetration of radionuclides into the sea waters from the additional radioactive sources is not excluded.

ABSTRACT

The article presents the measurement results of the volumetric activity (VA) of artificial radionuclides (90)Sr and (137)Cs in the coastal waters of the Baltic Sea near the Curonian Peninsula in 2005-2009. The annual average values for this period of time were 12 Bq/m(3) ((90)Sr) and 40 Bq/m(3) ((137)Cs). Considerable variations in the VA of the radionuclide in individual measurements compared to the average results were observed. The extreme values were 6 and 16 Bq/m(3) for (90)Sr and for (137)Cs-27 and 75 Bq/m(3). It is proposed to allow such variations under the influence of a variety of external factors such as hydro meteorological situations, inflowing rivers and bays, storm activity and etc. Besides, a possibility of penetration of radionuclides into the sea waters from the additional radioactive sources is not excluded.

Mentions: Simultaneous observations in VA of radionuclides near Juodkrante, Pervalka and Nida (Fig. 1) were carried out in July, 2008. In some cases a marked difference in VA of radionuclides was observed. The major variations of 137Cs VA took place on 4th July (Fig. 4) and 90Sr—on 6th July (Fig. 5).Fig. 4
